What are the major characteristics of savanna. Sahel and tropical rainforest's and how do they affect people's lives?

Answer 1

Savannas are characterized by grasslands with scattered trees, experiencing seasonal rainfall, which supports agriculture and livestock grazing for local communities. The Sahel, a semi-arid region south of the Sahara, faces challenges like desertification and variable rainfall, impacting food security and livelihoods. Tropical rainforests, rich in biodiversity and characterized by high rainfall and humidity, provide resources like timber and medicinal plants, but also face threats from deforestation, affecting indigenous cultures and global ecosystems. Each of these ecosystems influences local economies, agricultural practices, and cultural traditions, shaping the daily lives of the people who inhabit them.
